DGAO Advancement Award Aligner Orthodontics

DGAO research award for aligner orthodontics

The German Society for Aligner Orthodontics (DGAO) regularly awards a prize of up to 15.000 euros for scientific research projects in the field of aligner orthodontics.

Research Award

The DGAO research award is now a fixture in the orthodontic research landscape. It has been awarded every two years at the scientific congress for aligner orthodontics since 2012 and has been presented to 11 research groups so far.

Unpublished scientific research projects in the field of aligner orthodontics are awarded.

After the award ceremony, the award winners publish the result of their research project in the form of a poster, specialist article or lecture.

Individuals and research groups have until June 30, 2024 to apply for this year's DGAO funding award, which is endowed with 15.000 euros.
